  Preparation of Naphthoquinone Derivatives from Plumbagin and Their Ichthyotoxicity.

  摘要：

  各种萘醌衍生物是从天然产物5-羟基-2-甲基-1,4-萘醌（铅醌）中制备的；这些衍生物主要通过金属氧化剂（如醋酸铅四乙酯）在多种羧酸存在下，通过碳-碳键形成在C-3位进行取代。卤素化化合物的鱼毒性比铅醌更强，但其他衍生物的活性较低。

  The present disclosure relates in part to extracts of cranberry ( Vaccinium macrocarpon ) comprising an enriched amount of certain compounds having anti-infective activity, e.g. antibacterial and/or antifungal activity, e.g. activity against C. albicans . Another aspect of the disclosure relates to combined cranberry and cinnamon extracts. In certain embodiments, these combined extracts have been optimized to control urinary tract infections caused by E. coli, S. aureus and C. albicans . Certain embodiments of the extract are enriched in bioactive compounds that have been shown to inhibit C. albicans adhesion and/or biofilm formation and its growth in vitro. In another aspect of the disclosure, the extracts are enriched in bioactives derived from cranberry and cinnamon that have been shown to inhibit the attachment and the growth of common urinary tract pathogens like E. coli, S. aureus and C. albicans.

  Derivatives of plumbagin can be selectively cytotoxic to breast cancer cells. Derivative ‘A’ (Acetyl Plumbagin) has emerged as a lead molecule for testing against estrogen positive breast cancer and has shown low hepatotoxicity as well as overall lower toxicity in nude mice model. The toxicity of derivative ‘A’ was determined to be even lower than vehicle control (ALT and AST markers). The possible mechanism of action identified based on the microarray experiments and pathway mapping shows that derivative ‘A’ could be acting by altering the cholesterol-related mechanisms. The low toxicity profile of derivative ‘A’ highlights its possible role'as future anti-cancer drug and/or as an adjuvant drug to reduce the toxicity of highly toxic chemotherapeutic'drugs.
